GAS-REGULATOR.

Specification of Letters Patent.

Patented Dee 17, 1907.

Application filed March 20.1907. -.$erie1 No. 863.369-

' To all whom 'e't may concern:

- vide a novel device for regulating the pressure of gas as it passes through a meter.

Another object of this invention is to provide a simple and inexpensive, gas regulator adaptedto 'be-located upon a gas p1pe.be tween a meter and gas burner, our im roved 7 device being constructed to retard t e flow of gas in a pipe and automatically shut ofi the gas should the pressure of the same decreaseto apredeterniined point.

With the above and other objects in view, which will more readily appear as the invention is better understood, the same consists in the'novel construction, combination and arrangement of parts to'be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to the drawing forming art of this specification, like numerals of re erence designate corresponding parts throughout the several views, in which:

Figure 1 is a plan-of our im roved gas regulator, Fig. 2 is an end view 0 the "same, Fig. 3 is a vertical sectional view of theregulator, Fig. 4 is a cross sectional view of the same, 1g. 5 is a longitudinal sectional view of a regulator illustrating a modified form of construction, Fi 6 is a cross sectional view of the same, ig. 7 is a bottom plan, Fig. 8 is an elevation partly in section-of a movable head used in connection with the regulator.

To put our invention into practice, we ro-. vide a metallic body portion 1 substantially cylindrical, said body portion having a bore or cylinder 2, terminating in an interiorly threaded nipple 3. The opposite end of the bore or cylinder 2 is closed by a cap 4, said cap being suitably secured to the body portion 1 as at 5.

ates to gas regulators,

Formed within the body portion 1 and surrounding thebore or cylinder 2 is a chamber 6, said chamber communicating with an interiorly threaded nipple 7 formed at right angles to the nipple 3:

The side walls of the cylinder or bore 2 are provided with a lurality of circumferentially arranged oblbn'gopenin s or slots 8, said openings or slots establis g communication between the bore or cylinder 2 and the chamber '6. The top of the body portion 1 is provided with an "enlargement 9 having a compartment 10' formed therein, said compartment communicating with the chamber 6 and with the c linder or bore2. Detachabl A mounted int e enlargement 9 transverse y thereof are two sleeves 11, said sleeves extending into the compartment. 10.

J ournaled in the sleeves 11 is a shaft 12, said shaft being provided with a rectangular enlargement 14 between the ends of said sleeves, and surrounding said enlargement is the spanner end 15 of a lever 16, said lever extending downwardly through the compartment 10 into the bore or cylinder 2, where it has its end bifurcated as at 17, and slotted as at 18. One end of the shaft 12 protrudes outwardly over the body portion carrying an adjustable weight 20.

. In the bore or cylinder 2 is slidably mounted a head 21, said head carrying a central rearwardly extending sleeve 22, which telescopes a uide rod 23 carried centrally of the ca 4. H he rear end of the sleeve 22 is provi ed .with diametrically opposed pins 24, said pins extending into the slots 18 of the lever 16.

To place our improved regulator in use, the

gas plpe leading from the meter is connected to the nipple 3 while the pipe leading to the gas burner is connected to the nipple 7. The weighted arm 19 normally maintains the head 21 in the position illustrated in Fig. 3 of and is provided with a detachable arm 19 the drawings, said head closing the openings or slots 8 and cutting'ofl communication between the nipples 3 and 7. The pressure of gas assing into the nipple 3 and striking the head 21 is ada ted to move said head rearwardly a sufficient distance to allow gas to pass through the openings or slots 8 into the chamber 6 and the nipple 7, the distance said head is moved depending upon the pressure of the gas entering the ni ple 3. By adjusting the Weight 20 upon t e arm 19, the head 21 can be held at a certain tension to resist 5 and retard the gas entering the nipple 3, therefore preventing a free flow of gas that would otherwise take place if the head 21 was dispensed with. i By referring to Fig. 4 of the drawings, it will be observed that we form the cylinder or bore 2 eccentric with relation to thecylindrieal bodyportion 1, therefore providing free and ea'sypassage for the gas within the chamber 6,.towards'its exit, after the gas has passed through the openings or slots 8.

In Figs. 5 to 8 inclusive, we have illustrated a slight modification of our invention, wherein the weighted arm 19, shaft 12 and lever 16 are dispensed Withand the interior of the cylindrical body portion 1 slightl modified to conform to the structure whic we use in lieu of the Weighted arm 19. Instead of making the cylinder or bore 2, the entire length of the body ortion 1, we simply form a collar or cy 'ndrical shell 24 within the body portion, the chamber 6 being in direct communication with the interior of the ciylindrical body portion and the nipple 7. he collar 24 is provided with 0 enings. or slots similar to the openings or s ots 8' previously described, and in the bore or c linder 25 of said collar are mounted a hea and sleeve similar to the preferred form, said sleeve telescoping a guide rod 26 car- '35 ried by a cap 27, said cap being slightly different from the cap 3 insomuch as it is provided with a plug 28 having a conventional form of stufling box29. Extending through the stuffing box and plug is an adjustable rod 30, said rod being normally held in a fixed position by a screw 31. The rod protrudes mto the cylindrical body portion and-is provided with a head. 32surrounding the guide rod 26, said head bearing against the coiled spring 33 which surrounds the guide rod 26 and the sleeve 22. The coiled' spring 33 is employed to normally hold the head 21 in a seat 34 formed at the inner end of the nipple 3. The head 21 is adapted to'close the openings or slots 8 when the gas supplyis shut off, and move rearwardly when the gas is turned on. I

In the preferred form the position of the weight 20-u on: the arm l 'governs the flow of gas into't e nipple 7 while in the modified form, the tension of the spring 33 accomplishes the same purpose.

' It will be apparent from the illustration of our invention, that we have devised a simple and inexpensive structure for positlvely re-' tarding the flow of gas throughja meter,

thereby really decreasing the action of a meter and re ucing the expense of g gas as a fuel or for illuminating purposes. I

.with and with one ofsaid nipples, a cap Wedo not care to confine ourselves to the 66 two forms of our invention as illustrated, as various changes in the size, proportion and minor details of construction as are permissible by the ap ended claims, may be resorted to Without eparting from the spirit and scope of the invention.

What we claim and desire to secure by Letters Patent, is:
